Answer:
slope = m = 7/5
y-intercept = b = -3
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
y = 7/5 x - 3
slope = m = 7/5
y-intercept = b = -3
Step-by-step explanation:
MN=MP+PN
3X+2=5X-18
2X=20
X=10
MP=50
MN=32
NP=18
To find the population after t number of years, multiply the starting population by 1 plus the percent increase raised to the number of years.
The equation would be: P = 508(1.062)^t
Answer:
65.04<x<68.96
Step-by-step explanation:
The confidence interval formula is expressed as;
CI = x ± z*s/√n
x is the mean = 67
z is the 95% z score = 1.96
s is the standard deviation = 8
n is the sample size = 64
Substitute;
CI = 67 ± 1.96*8/√64
CI = 67 ± 1.96*8/8
CI = 67 ± 1.96
CI = (67-1.96, 67+1.96)
CI = (65.04, 68.96)
Hence the confidence interval for the mean of the population is between 65.04<x<68.96
Answer:
y = -2x + 9
Step-by-step explanation:
The equation of the new line is the same as that of this given line, EXCEPT that the constant will be different.
Start with y = mx + b; substitute 1 for y, 4 for x and -2 for m:
1 = -2(4) + b
Then b = 9, and y = -2x + 9
